REPRODUCING AND IMITA'IING MACHINE.

Specification of Letters Patent.

Patented Apr. 11, 1911.

To all whom it may concern:

Be it known that I, BENJAMIN O'i'ro FANSLOW, of the city of Los Angeles,1n the county of Los Angeles and State of California, have invented anew or Improved Reproducing and Imitating Machine, of which thefollowing 1s a full, clear, and exact specification, reference being hadto the annexed drawings and to the figures and letters marked thereon.

My said invention which relates to a new or improved machine forreproducing copies of documents, drawings, and pictorialrepresentations, has for its object to effect such reproduction byprinting operations, and by a machine having the special featureshereinafter described.

The machine constituting my present invention consists of a flatstationary base upon or within which there is carried either printingtype or other printing body or block, having upon its upper surface areproduction of any drawing, writing or pictorial representation in thestate capable of producing impressions from. At the upper parallel edgesat opposite sides of this flat stationary base a flange projects outwardfor a sufficient length of the base for the carriage of the impressionroller, and the impression roller to travel, and to be operated upon, inthe manner and by the means hereinafter described. In the under face ofeach of these flanges, a groove of various transverse sectional shapesis situated, and in these grooves, rollers constituting parts of themovable carriage which engage with the flanges, and which carriage alsocontains an impression roller, are retained in permanent operativerelationship, as hereafter set forth. The upper faces of these oppositeparallel flanges, one at each side of the base, are smooth, andconstitute level parallel guides or rails upon which rollers carried onstuds from the inner face of each side of the impression roller carriagepress and operate as next to be described. The carriage of theimpression roller, and the impression roller, are operated to and frofrom end to end of the machine at each printing operation, by means of acrank handle on the impression roller shaft, which being turned, causesthe impression roller to roll upon the paper upon one side of which theimpressions or reproductions of type or other surface capable of beingprinted from are to be made. The paper is pressed by the impressionroller in the course of each successive travel upon the upper surfaceofthe printing ribbon, and the printing ribbon simultaneously pressed uponthe type or other surface in the base of the machine capable of beingprinted from.

The arrangement of my new or improved machine is generally such that itmay be operated rigidly, with ease, certainty, and economy in theproduction of copies of original documents, drawings or otherrepresentations.

Upon the annexed drawings Figure 1, is a side elevation of the machineconstituting my invention. Fig. 2, is a longitudinal section thereofupon the line a, a, Fig. 3. Fig. 8, is a plan partly in section,corresponding to Figs. 1, and 2. Fig. 4, is an end elevation of themachine looking in the direction of the arrow X, Figs. 1, 2, and 3. Fig.5, is a transverse section on the line b, 6, Figs. 1, and 2. Fig.7 6, isan end elevation of a modification of the carriage showing the rollerswhich bear upon the smooth upper face of the flange of the base, theserollers being carried adjustably as hereinafter described. Fig. 7 is anend elevation of a portion of the machine corresponding to Fig. 6. Fig.8, is another plan of a modification of the machine in which the rows ofprinting type are contained in the chase, or type holder, in a positionat right angles to the position shown in Fig. 3, the machine being inall other respects identical with that shown in Fig. 3, excepting thatthe entire machine is of greater width than that shown in Fig. 3, so asto accommodate the chase, or type holder to be placed with the rows oftype in either of the directions shown at Figs. 3, and 8, respectively.

In Figs. 1, 2, 3, 4;, and 5, of the drawings, the horizontal baseportion is marked A, and it is shown as consisting of a flat plate ofcast iron or equivalent material, whose upper surface is planed true andlevel, havinga vertical upward projection B, at each side thereof. Theupper part of the projection B, is formed with a longitudinal flangeportion G, as shown more particularly at Figs. 1, 4., and 5. In theunder part of each flange portion 0, of the sides of the base A, thereis'a groove D, preferably V-shaped as shown at Figs. 4, and 5. Thecarriage E, of the impression roller at its lower part is bi-furcated,each bi-furcation E, and E, respectively, having a pin F, therein uponeach of which is carried an anti-friction roller G. Each of theseantifriction rollers G, engages with the groove D, in the under part ofeach flange portion C. Higher up in the bi-furcated portions E, of eachof the ends of the carriage of the impression roller H, there aresituated rollers I, I, each of which rollers is carried upon a pin J,fastened into each side or end of the carriage E. 'As shown by Figs. 1,2, 3, and 4, the pins F, upon which the lower rollers G, are carried,and the pins J, upon which the upper rollers I, are carried, are heldrigidly in the bi-furcated portions of each end of the carriage E, butthey may be provided with means for adjustment of the rollers inrelationship to the grooves D, and the upper flat surface of the flangeC, as hereinafter described. As will be obvious on inspecting thedrawings, Figs. 1, 2, 3, 4L, and 5, the carriage E, is wholly supportedby the lateral upwardly projecting portions B, and the flanges C, ateach side of the base A, while guidance to prevent the carriage E, fromshifting laterally, or out of parallel with the length of the base A, isobtained by reason of the lower rollers G, being engaged with theV-shaped or equivalent grooves D, in the under part of the flanges C.

From the arrangement and construction hereinbefore described, it will beseen that the impression roller H, in no respect bears upon the sides B,and the flanges O, projecting upward at each side of the base A, andthat the impression roller is carried wholly upon its shaft K, in theadjustable bearing blocks L, one at each side or end of the carriage E,so that while the impression roller H, rolls freely in its bearings inthe carriage E, it has no contact whatever with the rails or guidesconstituted by the flanges G, and grooves D, with which the rollers G,and I, engage, and by which alone the carriage E, is operativelyconnected with the base of the machine which carries the type M, orother printing surface in the central, level and lower part of the baseA.

The type M, shown in Figs. 2, and 3, is held in the chase N, by means ofthe furniture O, and P, respectively, being pressed against the endplates Q, which are situated between the rows of types M, when set inthe chase N. The furniture 0, and 1 is pushed against the types M, so asto tighten them within the chase N, by the wedges R, and S, in the usualmanner by insertingthe teeth of a quoin key, (not shown in the drawings,but well understood) into and between the toothed racks of the wedges R,and S, which toothed racks are shown in Figs. 2, and 3. The inkingribbon T, is

carried upon the rollers U, and V, respectively, in the inclinedbearings U, and V, formed one in each end of the base A, and theserollers are maintained in their places in the inclined bearings U, andV, by means of the rubber plugs U and V which. areinserted and pressedinto their place by hand, one in the upper part of each of the inclinedbearings U, and V. The under part of the rubber plugs U and V is formedcircular so as to more or less correspond with the bearings of theinking ribbon rollers U, and V, and when pressed into their inclinedspaces in the ends of the base A, as shown at Figs. 1, 2, and 3, notonly act as the upper part of the bearings for the inking ribbon rollersU, and V, but by being pressed into the inclined spaces with sufficientforce they are caused to bear and remain with the requisite pressureupon the journals of the inking ribbon rollers U, and V, so as toproduce the requisite drag upon the printing ribbon rollers necessary tomaintain the requisite tightness of the inking ribbon T, in itsoperation, and stretch the same over the surface of type or otherprinting surface at any time when being used in my said machine.

The ratchet wheels W, one on one end of each inking ribbon roller U, orV, are operated by the pawls Y, and Y, pivotally carried and pointing inopposite directions by each bi-furcation of the carriage E, and at' oneside thereof as shown at Figs. 1, 3, and 4. Each pawl Y, or Y, as itengages with the teeth of each ratchet wheel W, causes the necessaryrotation of the corresponding printing roller U, or V, at thetermination of each stroke of the carriage E, and impression roller H,so as to wind on, or off, either printing ribbon roller U, or V, arequisite length of printing ribbon T, to present a fresh surface ofprinting ribbon to the type or other surface being printed from at eachto and fro traverse of the carriage and printing roller. So that theextent of winding and unwinding of the ribbon T, off, and on, to theribbon rollers U, and V, may be varied from time to time, as requiredeach of the machines as constructed according to my invention isprovided with a set of pawls Y, and Y, of different lengths so thattheir outer ends may engage with the teeth of the ratchet wheels WV, atany regulated distance before each to and fro travel of the carriage andimpression roller terminates; this distance being determined by thelengths of the pawls Y and Y, at the time in use, a longer pawl movingthe ratchet wheels W, througha greater angle of rotation than a shorterpawl can; the movement caused by the longer pawl being suflicient tounwind a length of ribbon more than that which is necessary to provide afresh surface of ribbon to print from, While the movement of the shorterpawl alternating with the movement of the longer pawl winds back theportion of this ribbon which has. been last printed from, thus enablingthe succeeding printing operation to be efiected from the fresh portionof the printing ribbon situated between the portion of the ribbonlastprinted from and the used portion of the ribbon being wound on thewinding up ribbon roller. The termination of the travel of the carriageE, and impression roller H, in either direction is fixed by means of thestuds Z, toward each end of each side of the flanges C.

To enable the rollers I, I, and G, G, to be adjusted in theirrelationship to the grooves in the flange C, and to the upper face ofthe flange C, respectively, the upper rollers are carried on pins orbearings I, I, in a bar Z, as shown at Figs. 6 and 7. A bar Z, isattached to each end of the carriage E, as shown at Figs. 6 and 7, byadjustment bolts and nuts Z, Z, respectively. By loosening the nuts ofthe bolts Z, r and pressing the rollers I, I, and Gr, G, as close aspossible to the top flat surface of the flange C, and the groove D, inthe under part of the flange, any desired adjustment of contact of therollers I, I, and G, G with the engaging parts of the flange iseffected, and by tightening the nuts Z, Z, this adjusted relationship ofthe rollers I, I, and G, G, with the flanges C, and the grooves D, ismaintained.

My machine as shown at Fig. 8, is in all respects the same as themachines hereinbefore described, and shown at Figs. 1, 2, 3, 4, and 5,excepting that in the machine shown at Fig. 8, provision is made forenabling the rows of type M, to be placed in the chase, or type holderN, at right angles to the position which the rows of type occupy asshown by Figs. 2, 3, and 5, and to enable this change of position of thetype to be effected, the base A, of the machine and all partsconstituting the base, as well as the flanges G, and the sides B,thereof, are made sufficiently broad to enable the chase, or type holderto be placed within the base A, in Fig. 8, at right angles to theposition in which it is shown as situated in Figs. 2, 3, and 5. Thecarriage E, and the impression roller H, are correspondingly longer. Allthe parts constituting my machine as shown in Fig. 8, are letteredcorresponding to the same parts in Figs. 1, 2, 3, 4, and 5, andtherefore need not be herein further referred to. The operation of themoving parts of the machine being in all respects identical with thathereinbefore set forth respecting Figs. 1, 2, 3, 4, and 5.

I claim as my invention 1. In combination with the frame of aduplicating machine having parallel tracks with a groove in the bottomof each, a carriage having a plurality of anti-friction rolls onopposite ends thereof, certain of which cooperate with the grooves andcertain of which cooperate with the said tracks whereby to embrace thelatter and maintain the carriage thereon,- an impression-rollerjournaled in said carriage, ribbon-reels supported one at each end ofthe tracks, means on the carriage for actuating said reels, and meansfor rotating the said roller and simultaneously driving the carriagealong the frame, whereby also the reels will be actuated by the carriageat each end of its travel.

2. In combination with the frame of a printing machine, provided withparallel tracks, a carriage provided with anti-friction rollscooperating with said tracks, an impression-r01 er journaled in thecarriage, means for actuating the impression-roller and simultaneouslydriving the carriage along the frame, ribbon-reels supported at oppositeextremes of the travel of said carriage, and driving means of differentlengths supported by the carriage for cooperating with the reels at theopposite extremes of travel of the carriage whereby to rotate said reelsvarying distances, substantially as described.

In testimony Whereof, I have hereunto set my hand and seal in thepresence of two subscribing witnesses.
